Question:

Which of the following are first-line drug(s) for acute symptomatic bradycardia?

a.Vasopressin

b.Dopamine

c.Epinephrine

d.Atropine

e.Answers c. and d.

Answer:

d. Atropine

Question:

Which heart rate parameter does the AHA use to define bradycardia?

a.< 45 beats per minute

b.< 50 beats per minute

c.< 55 beats per minute

d.< 60 beats per minute

Answer:

b. < 50 beats per minute

"Bradycardia is defined as a heart rate of < 60 beats per minute. However, when bradycardia is the cause of symptoms, the rate is generally < 50 beats per minute, which is the working definition of bradycardia used here (Figure 3, Box 1)."(page S748 Adult Advanced Cardiovascular Life Support: 2010 American Heart Association Guidelines for Cardiopulmonary Resuscitation and Emergency Cardiovascular Care)

Question:

Which of the following drug(s) can be considered for symptomatic bradycardia unresponsive to atropine?

a.Dopamine

b.Epinephrine

c.Isoproterenol

d.All of the above

e.Answers a. and b.

Answer:

d. All of the above

"Although not first-line agents for treatment of symptomatic bradycardia, dopamine, epinephrine, and isoproterenol are alternatives when a bradyarrhythmia is unresponsive to or inappropriate for treatment with atropine, or as a temporizing measure while awaiting the availability of a pacemaker. Alternative drugs may also be appropriate in special circumstances such as the overdose of a Beta-blocker or calcium channel blocker."(page S750 Adult Advanced Cardiovascular Life Support: 2010 American Heart Association Guidelines for Cardiopulmonary Resuscitation and Emergency Cardiovascular Care)

Question:

Which drug has been removed from the Asystole/PEA AHA 2010 Guidelines?

a.

Isoproterenol

b.

Atropine

c.

Dopamine

d.

Answers a. and b.

Answer:

b. Atropine

"Available evidence suggests that the routine use of atropine during PEA or asystole is unlikely to have a therapeutic benefit (Class IIb,LOE B). For this reason atropine has been removed from the cardiac arrest algorithm."(S739, Adult Advanced Cardiovascular Life Support: 2010 American Heart Association Guidelines for Cardiopulmonary Resuscitation and Emergency Cardiovascular Care)

Question:

Which are vasopressor benefits in cardiac arrest?

a.

Increased myocardial blood flow

b.

Increased cerebral blood flow

c.

Speeds up PEA rhythms

d.

All the above

e.

Answers a. and b.

Answer:

e. Answers a. and b.
